Study Notes
Nucleophilic Substitution Reactions
- The nucleophile donates a pair of electrons to the substrate, facilitating the substitution reaction.
- The concerted mechanism, known as S_N2, involves a simultaneous bond-making and bond-breaking process, where the nucleophile attacks the substrate as the leaving group departs.
- In nucleophilic substitution reactions, the bond between the carbon atom and the leaving group is broken concurrently with the formation of a new bond between the carbon and the nucleophile.
- In the stepwise mechanism, known as S_N1, the rate-determining step is the formation of the carbocation intermediate, which occurs after the leaving group's departure.
